An open flask sitting in a lab refrigerator looks empty, but it is actually filled with a mixture of gases called air. If the flask volume is 1.50 L, and the air is at standard temperature and pressure, how many gaseous molecules does the flask contain? number of gaseous molecules:
Homework Answers
Molecules are calculated:
molecules = P * V * NA / R * T = 1 atm * 1.5 L * 6.02x10 ^ 23 molecules / mol / 0.082 atm * L / mol * K * 273 K = 4.03x10 ^ 22 air molecules.
If you liked the answer, please rate it in a positive way, you would help me a lot, thank you.

When conducting an experiment, it is important to have a hypothesis in mind and know what variables you will be looking at to help you in your testing. Ordinarily a scientist will perform a sort of experimental design before beginning any lab work. To gain some experience with this type of work, complete and attach an Experimental Design Worksheet for this experiment. Please use the worksheet provided under this experiment on Canvas.
